Sponsor: MAPS, Dept. of Psychiatry Hannover Medical School
Clinical experiment with ketamine to establish a paradigm to use visual 3-D illusions as screening instruments for detecting psychedelic activity in humans below the subjective threshold of experience. Passie’s team has recently published a report relating to this research. A second report on data from this MAPS-supported study will soon appear in the journal “Neuropsychobiology” in early 2005.
